[moved] Applying a digital sinewave in Xilinx ISE

[himadri_debnath]

I want to apply a digital sine wave of different frequencies as an input to an 64bit register in Verilog (Xilinx ISE). How to do that? Is there any way to generate digital sinewave in Matlab and then apply the data in Xilinx?

Use a "ROM" and index through the ROM at the frequency you need to output.

A DDS generator is a versatile way to get a continuously variable frequency.
